Since you struggle so much with reading, I will read it for you:

> UPE, also known as biophoton emission, is a spontaneous release of extremely low-intensity light that is invisible to the human eye and falls within the spectral range of 200–1,000 nm.

UPE is due to oxidative stress. In contrast, the wavelength of IR is 700 nm to 1 mm. IR is fundamentally different altogether than UPE.
